I E. BAKER, a *c1t1zenof the U'n-ited Stat-es, residing at Napa city, in the county of Napa and State of California, haveinvented new and useful Improve'mentsin Antislipping Devices for 1ghoes, of which the followingis a specifica- The, invention relates to anti-slipping declass of sole and heel calk attachments. ,The' primary object of the invention is the provision of an anti-slippin device of this characterwhich is especial y adapted foruse on' the shoes of woodsmen in' the lumbering' camps and also baggers and on the j. river drives so as to give positive footingto such persons -whileatwork.

Another object of the invention is the proj be readily mounted upon and detached froin footwear, and when the device is in use will prevent. the pedestrian from slipping while walking-over ice or climbing hill sides, thus assuring a positive tread when walking upon slippery surfaces with the same assurance as upon the streetj or pavement under ordinary conditions." vA ftirtherobject of j I the invention is the go provision ofa device 'of this character which maybe adjustedtovarying sized footwear,

' whereby thereonv for use in walking upon slippery surfaces, thus avoiding" the slipping of the pedestrian as would ordinarily occur should the device be not present upon the footwear. A further object of the invention is the provision of a device of this character which is simple of'construction, strong, readily and wear, and that'may be manufactured at a minimum expense.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter .more fully described, illustrated inthe accompanying drawings, andpointed out in the claims hereunto appended. sti 1in the drawings: Figure 1 1s a bottom plan view :of a shoe, showing the anti-slipping device appliedboth to the'heel and sole thereof. Fig. 2 is a side elevat1on. Fig. 3 1s a perspective viewofthc anti-slipping device for the heel of a shoe, the-same being shown removed therefrom.

Vices for shoes, and more particularly to the well-known construction, and to which are attached the sole and heel anti-slipping devision of an anti-slipping device which may.

formed whi=le the section 5 is further provided at its the same may be securely clamped easily applied to and detached from foot 'mounted inthe section 6 which Fig. 4 is a per- I spective view of the anti-slipping device for the sole of the shoe, the same being removed therefrom. Fig. 5 is a sectionalview j on the line 55 of Fig.1.

Similar reference characters indicate -correspo difigparts throughout "the severalr v gsfi Referring to the drawings by numerals, 2

designates generally a shoe having a sole 3 and a heel 1, the same being of theordinary vices, as w ll be hereinafter more fully de-' scribed.

The sole anti-slipping device comprises a pan-of sections-5 and 6,eac h being formed from a single piece of sheett metal cut out, as at 7, to lighten the weight thereof, .the sections being connected at the toe by means of'a pivot 8, whereby they may be adjusted toward and away from each other. At the opposite ends ofuthese sections 5and6' are outer cylindrical-shaped sleeves 9,

inner end with an intermediate cylindrical shaped sleeve 10, the same alining with the sleeves 9- and through which ispassed an adjusting boltmember' 11 provided at one end with a squared head 12 to be engaged by a suitable key for the turning thereof, while its opposite end is provided with threads 13 adapted for adjustable engagement with internal threads 14 formed in the sleeve 9 on the section 6.- Thus it will be seen that on the turning of the bolt member 11, the sections 5 and 6' maybe adjusted toward and away from each other, as the occasion may require.

: Struck up from'the outside edges of the sections 5 and 6 at intervals are gripping ears or clips 15, the

same being provided with inturned free extremities 16. the clips 15 being adapted to engage' with the peripheral edge of 'the sole of the shoe, and their inturned free extremities 16 will overhang the upper surface of the sole, so'that when the bolt member .11 is turned in one direction the sectionswill be securely 'clampedto the sole.

are notches 17-, in which are engaged lugs 18 serve as swinging stops for limiting the inward movement of the sections toward each other.

the same being adapted to engage with the' heel 7 of the shoe for the'mounting of the sections thereon on adjustment of the bolt 27 v, for moving the sect1ons20 and 21 together, or toward each other. Rweted or otherwise secured to the onter faces of the sections 20,
